Title: Solvent for 2,5-DMA
Post by: GammaQ on January 03, 2003, 03:13:00 AM

What other solvent can I use to synthesis the 2,5-DMA besides the CHCl3 ??

RGDS !

You need to specify which route you are planning to use, otherwise it´s kinda hard to know which solvents are useful.

Title: 2,5-dimethoxynitropropene preparation improvement
Post by: Rhodium on January 03, 2003, 04:44:00 AM

Instead of using the messy preparation from Pihkal requiring solvent extraction to synthesize the 2,5-dimethoxynitropropene, instead use the procedure at

https://www.thevespiary.org/rhodium/Rhodium/chemistry/edda.html (https://www.thevespiary.org/rhodium/Rhodium/chemistry/edda.html)

which gives an equal yield, higher purity, and also produces the 2,5-dimethoxynitropropene in crystalline form directly.

If you still feel you want to use the Pihkal procedure, you can substitute the chloroform with dichloromethane.
